The 15 Most Expensive Places To Buy Gas In The World

Americans are fretting over the rising cost of gasoline, and are now paying above $4 a gallon for gas in some spots in the country.

But that $4 a gallon number is nothing compared to some corners of the earth, where high taxes drive gas prices higher.
